Changing Last Name with Business

I always thought I would change my last name with no hesitation. 😅 I own a business on the side and decided to order business cards for it. FH helped me design them and naturally we put my name as it is now. We ordered 500 of them and then had an “oh crap” moment when we realized I would only be using them for 3 months before my name change and definitely would not go through all 500. FH cancelled the order. Now I need to reorder and I’m so hesitant as to what I should do. I don’t like the way my new name looks on the card. FH wants me to change my last name and I always said I did and still want to change it to make things less complicated especially with kids. Would it be a problem to keep my last name as is for my business? Or if my legal name changes, will I run into problems using it (for example, if someone gives me a check with maiden name)? Or would it be best to go ahead and use my new last name on everything while the business is still young? If I change my last name, my initials will be G.E.M. which I looooove. But if I keep my maiden name, my first and last name both start with a G which has a nicer sound to it. Would appreciate any advice, especially for those who have a business!
